AMOS B. BUCKLAND, OF ROCHESTER, NEW YORK.

DOOR-SECURER.

SPECIFICATION forming part of Letters Patent No. 526,683, dated October2, 1894.

Application filed May 24, 1894. Serial No. 512,323. (N 0 model.)

To all whom it may concern.-

Be it known that I, AMos B. BUCKLAND, a citizen of the United States,residing at Rochester, in the county of Monroe and State of New York,have invented certain 'new and useful Improvements in Door-Securers; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention has relation to locks or keys, for doors or as I term itcombined locks and keys, and among the objects in view is to provide adevice which will be-adapted to serve for lockin g a doorin its closedposition whether said door is provided with the usual lock and key ornot whereby it will be impossible for a door to be opened from theoutside even if the usual lock is picked or turned by its key.

A further object of my invention is to provide means for preventingaccidental turning of my combined lock and key from its lookingposition.

Other objects and advantages will be apparent from the followingdescription, and with the Various objects in view my invention consistsin the novel construction of the device and in its combination with adoor and jarnb as hereinafter fully described, illustrated ip thedrawings and poiutedout in the appended claim.

In the drawingsz-Figure 1 is a detail perspective View of the combinedlock and key. Fig. 2 is a face view of a portion of a door jamb showingthe device inserted but before being turned to lock the door. Fig. 3 isa similar view showing the device in its locking position. Fig. 4 is afront View showing the door closed and locked by the device. Fig. 5 is ahorizontal sectional view of the parts in their locked position.

1 indicates my device, which I term a combined lock and key, the sameconsisting of thering or operating portion 2, shank 3, and bit or head4. In constructing these parts of the device, I make the shank of smallcrosssectional area or diameter whereby to adapt said shank to be passedin between the edge of the door and the face of the jamb as seen in Fig.4, such space being as well known usually quite small. I also bend theshank at a point adjacent to the ring whereby to permit the easyinsertion of the device in place without danger of the door injuring thefingers when it is closed. The length of the shank will of course bevaried to suit doors of various thicknesses, it being necessary to makeit of such length that the ring will be beyond the j amb when the head 4lies within the recess in the said jamb as seen in Figs. 2 and 3.

The head of the device I preferably make of substantially lozenge ordiamond shape, whereby when the said head is in position the side orface 5 will lie snugly against the face 6 of the notch in the door jamband the face 7 of the head will lie snugly against the inclined face 8of the latch-bolt as seen in Fig. 5.

In order that the head of the device will not offer any obstruction tothe closing of the door I locate the head to one side of the line of theshank so that the head will lie entirely within the recess of the jamband allow the door to be fully closed.

In using my device I placethe head thereof within the recess of the jambas seen in Fig. 2, with the shank extending alongside the face of thejamb. The door is now closed and when in its fully closed position theperson turns the key or look 1, one-fourth of a turn which brings thehead in a position to partly engage behind the latch bolt and partlywithin the recess of the jamb as seen in Fig. 5. It will now beimpossible to open the door from the outside, the device forming aperfect lock therefor.

When it is desired to open the door from the inside the device is turnedback into its position seen in Fig. 2 after which the door may bereadily opened.

In order to prevent the device being accidentally turned from itslocking position, I provide an elastic band 9, which is passed over thering of the device and over the door knob 10.

It will be seen that my device may be used with doors provided with theusual lock and key or not, the same not interfering in any way with theoperation of said usual lock and key, and when the latter are used, mydevice provides an additional security against the opening of the doorsurreptitiously.

It will also be seen that my device is adapted for use with both rightand left hand doors ICO by simply reversing the bend in the shank andthe diamond or lozenge shaped head or 15 and locating the head uponopposite sides of bit 4,'the face 5 whereof is adapted to lie thelatter. against the face 6 of the notch in the door- What I claim, anddesire to secure by Letjamb and the face 7 against the inclined face 5ters Patent, is 8 of the latch-bolt, said head or bit of the de- Thecombination witha door provided with vice 1-, being arranged to one sideof the line 20 a latch-bolt opening, and a lat'ch-bolta'dapted of theshank for the purpose specified. to operate therein and having aninclined face In testimony whereof I affix my signature in ii, an]? adoor-jamb provided with a triangug presence of two witnesses.
